Ответ:
In order to find the slope given two points, we use our formula:
y2-y1/x2-x1
Therefore, we have:
(3, -6) and (-2, -4) which gets us
-4-(-6)/-2-3
Therefore, our answer is A.
Hopefully this helps!
Ответ:
sqrt( 146)
Step-by-step explanation:
To find the distance, we use the following formula
d = sqrt( ( x2-x1) ^2 + ( y2-y1) ^2)
sqrt( ( -9-2) ^2 + ( 0-5) ^2)
sqrt( ( -11) ^2 + ( -5) ^2)
sqrt( 121+25)
sqrt( 146)
